Zucchini EdM cast resin transformers -...

EdM transformers are the high quality solution for many types of applications...

designed and manufactured in accordance with national and international standards.

EdM cast resin transformers are used in a vast range of

applications and, with over 50 years history, are a reliable

answer for distribution systems, energy co-generation,

rectifi cation, traction and other special requirements.

REDUCED ENVIRONMENTAL IMPACT

The absence of infl ammable insulating liquids, the self-

extinguishing materials exempt of toxic gas emissions and

the low noise levels and low electromagnetic emissions all

combine to present a responsible solution to environmental

protection and public security.

1. MV windings in aluminium strip coils, cast in resin

under vacuum.

2. Core in three columns in magnetic lamination with

high-permeability oriented crystals, also available

with low losses.

3. LV windings in aluminium plate/sheet and

vacuum-cast impregnated insulation material.

4. LV connections upwards (standard) or downwards

(on request).

5. MV connections upwards (standard) or downwards

(on request).

6. Rubber inserts attenuate the transmission of

vibrations between core and windings and reduce

operating noise generated by the transformer

to a minimum, as well as absorbing the thermal

expansion of the components.

7. Sockets on the MV side can adapt the primary

voltage to the mains when the transformer is

switched off.

8. Structure, armatures and carriage manufactured

from strong painted sheet steel.

9. Carriage with bi-directional castors.

10. The epoxy resin insulation makes the transformer

low maintenance.

11. The operating temperature is checked by Pt100

sensor or PTC in the LV windings.

12. Lifting eyebolts conform to the DIN-580 UNI-2947

standards with safety hooking at 4 points.

13. Optional pre-equipment for connection of the LV

connection to Zucchini busbar trunking system.

14. Class F insulating material, at 155°C, allowing for a

temperature rise of 100°K. (100°C)

15. The carriage allows safe movement and is

pre-equipped for the mounting of IP reinforced

boxes.

EdM cast resin transformers medium voltagestandards and technology overview

■ Certified quality standardsThe safety and continuity of operation of the specific users dependessentially on the reliability of the transformers installedEdM cast resin transformers have been designed and manufacturedaccording to the provisions laid down by the main national andinternational standards

Reference standardsIEC 60076-11 (2004) :Dry-type power transformers

IEC 60076 Power transformers

HD 538.1 S1 (1992) Dry-type transformers enclosed in resin with insulation up to class 36 KV

Tests and inspectionBefore the cast resin transformers produced by EdM are supplied to thecustomer, they are individually inspected thus eventually passing theacceptance and type-approval tests, if expressly requested whenorderingAt the end of the acceptance tests a specific inspection report isattached to each transformer with all executed checksBoth the ordering company and any final customer can reserve the rightto be present at the inspections in the EdM test room (attendedinspections) and, on prior notification with the productive unit, can makeinspection visits before and during the manufacturing of the order

■ The EdM technology

Medium voltage windingThe medium-voltage winding, made by highly automated windingmachines, is constructed with the continuous disk technique and madein aluminium strip, interleaved with double insulationThis type of working produces uniformity of the internal and externalthickness of the resin and guarantees uniform resistance to thedielectric stresses to which the transformer will be subjected in theinspection phase or during its operation at the place of installation

The primary winding has sockets to adjust the primary voltage equal tothe value ± 2 x 2·5%, made with brass bushes protruding from theresin, copper nuts and bolts and indelible numberingThe insulating materials used belong to class F and the permittedtemperature rises are those specified in Standards IEC 60076-11

Low voltage windingThe low voltage winding, made with special automatic windingmachines, consists of one aluminium strip with an intermediate class For class H insulating sheetThis solution gives the winding a certain compactness capable offorming a one-piece cylinder that can withstand possible axial andradial stresses resulting from short circuit phenomena within the systemand at the downstream side of the transformer

All the welds of the conductor strip with the output bars are made bybutt welding in inert atmosphere and under electronic control, so as toavoid possible damageThis winding is then vacuum-impregnated with epoxy resin so as to giveit the required compactness and uniformity and to avoid the absorptionof humidity throughout the life of the machine, whatever environment itneeds to operate inThis treatment also allows EdM cast resin transformers to comply withthe F1 classification according to the standards and IEC 60076-11

■ The CLE range (certified low electromagnetic emission)CLE transformers (certified low electromagnetic emissions) arespecifically designed and built for reducing electromagnetic emissions.This is the ideal solution for places continuously attended by people or,for example, with particularly sensitive electronic equipment As a result, the EdM CLE range is fully in compliance with the DPCMregulations of 8/7/2003 (electromagnetic emissions lower than 10microTesla), and the EdM quality target” is set to a threshold of 3microTesla EdM provides each CLE cast resin transformer with a specificmeasurement ratio of the electromagnetic emissions

Furthermore, by using a modern semi-anechoic chamber located insidethe EdM laboratory, the CLE transformation systems can also besupplied with a noise measurement ratio based on different emissionbands

Ventilation accessoriesEdM can be equipped at the factory with special ventilation bars These special tangential fans are designed to allow temporary andlimited increase of the power delivered by the transformer, up to + 40%of the rated power

VRT200 Unit : equipment for automatic activation and control of thefans

■ EdM: a system under control - temperature andventilation surveillance

Temperature surveillance toolsEdM gives you the possibility of combining all its transformers of anysize with the best temperature detection tools now available on themarket

Thermal sensors - PT100 : positioned by EdM near the warmest areaof the winding, they can be programmed according to the specificrequirements of any installation

PTC thermistors : positioned by EdM near the warmest area of thewinding, their preset alarm threshold and trip threshold are chosen bythe customer when the order is placed

The wiring of the connections used for the temperature sensors isprotected and screened by a special metal plate conduit andconnected to a terminal board installed inside a strong metallic box

When combined with control sensors, EdM can also supply thefollowing, if required :

T154 Unit or MT200 Unit : equipment used for controlling the PT100thermistors with temperature display, output relay for alarm, optional tripand control of the ventilation bars supplied as a detached part to beinstalled on the electric panel

T119 Unit : equipment used for controlling the PTC thermistors withoutput relay for alarm, optional trip and control of the ventilation barssupplied for being installed on the electric panel

■ The EdM technologyEdM is distinguished by its high-quality production. Using state-of-the-art construction techniques and equipment, and with constant attentionthroughout the production process (ISO 9001 : 2008) and a rigorouscheck in the final phase, guarantees quality throughout the entireprocess

EdM cast resin transformers installation information

■ Installing an EdM transformer EdM cast resin transformers can be installed quickly and easilySince no additional construction or building activities are necessary, safe installation can be ensured by following a few simple steps :

• Standard execution – indoor installation, in dry / clean environments, protected from direct sunlight, with no possibility of water ingress

• Altitude no higher than 1 000 m above sea level (for higher installations, contact us on +44 (0) 845 600 6266)

• Room temperature with transformer in operation (for higher values, contact us on +44 (0) 845 600 6266) :•T minimum – 25°C•T maximum + 40°C

• With a standard execution, the transformers are designed in accordance with the IEC Standards 60076-11 for the following room air temperatures :• 40°C at peak times• 30°C as a monthly average in the warmest month• 20°C as a yearly average

• In order to protect the transformers from external environment impacts and people from the risk of having direct contacts, a set of standardboxes is available with different degrees of protection : IP 21 / IP 31 / IP 23
